BOB SLED.

SPECIFICATION forming part of Letters Patent No. 433,742, dated August 5, 1890..

Application filed February 27, 1890. Serial No. 341,936. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW NnwsrRoM, a citizen of the United States, residing at Red I Ving, in the county of Goodhue and State of Minnesota, have invented certain new and useful Improvements in Bob-Sleds; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in bob-sleds; and the nature of the invention will be understood from the following description, when taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of the runninggear of a sled; Fig. 2, a view in perspective, on an enlarged scale, showing the bearing for the axle; Fig. 3, a detail elevation showing connection of the tongue and front runners, and Fig. 4: a similar view showing connection between rear runners and a semicircular bail connecting such runners and the reach.

This invention is an improvement over that shown in Letters Patent No. 341,679, issued to me on the 11th day of May, 1886.

In the drawings, A A represent the front runners and B B the rear runners. C is the reach; D, a fifth-wheel; E E, bolsters connected by hounds F, and G suitable strengthening-irons bolted to the runners.

II represents a bracket, one of which is mounted upon each of the forward runners, each such bracket at its lower end overlapping the sides of the runners, as shown at a. Each bracket is provided with three posts 1, 2, and 3, posts 1 and 3 being bored vertically for the passage therethrough of bolts I, such bolt-s passing through the runners at their lower ends and througlr acap J at their upper ends, the parts being heldtogether by nuts. That part of the bracket immediately above post 2 is hollowed out to form a semicircular depression b, the center of cap J be in g constructed with semicircular raised portion 0 to register therewith and form a bearing for the end of the axle K. The bracket is formed with a horizontal lip or flangeL 011 its innertace, the axle resting upon this flange and secured thereto by a suitable bolt passed through the axle and flange. The axle may also be more securely connected with the bearing by means of suitable skein-bolts d, Fig. 2.

M represents the tongue, and M a crosspiece connected therewith. At each end of the cross-piece M is provided a bolt. 6, provided at one end with an eyelet, through which a bolt f is passed, such bolt being also passed through the runner and through a bracket N, secured to the runner.

0 represents the semicircular bail connecting the reach and the rear runners. This bail is connected with the reach, as described in my former patent, and to the runners by the same means as described in connection with the tongue.

lVhat I claim is- 1. In a bob-sled, the combination, with the runners and brackets H mounted thereon, such brackets formed with posts 1 2 3 and semicircular depression I), the posts 1 and 3 being bored vertically, of axle K and cap J the latter provided with the semicircular raised portion 0, registering with the depression 1) of the brackets, and the bolts inserted through the cap and the bored posts 1 and 3, as set forth.

2. In a bob-sled, the combination, with frontrunners and brackets II mounted thereon, such brackets provided with postsl 2 3, semicircular depression b, and lip or flange L, of cap .I and axle K, the cap and bracket connected by bolts, and the axle and lip or flange connected by other bolts, as set forth.

In testimonywhereof Iaflix my signature in presence of two Witnesses.

ANDREW NEWSTROM.
